摘　　要：以一种新型双履带工程车辆电传动驱动桥为研究对象,通过Romax软件建立驱动桥传动系统模型,利用齿轮微观修形优化来提高驱动桥传动平稳性,减小振动冲击。通过对驱动桥齿轮进行齿向和齿廓修形优化,减小了齿面最大单位载荷,齿面应力分布更加均匀合理,齿轮的啮合性能得到改善。优化后驱动桥振动谐波幅值下降了约26.17%,减弱了齿轮传动过程中向外辐射的振动噪声,实现了电传动驱动桥的减振降噪。Taking a new electric drive axle of the double-crawler engineering vehicle as the research object,a model of the axle drive system is established by software Romax,and gear micro-modification optimization is used to improve the drive stability of the drive axle and reduce vibration impacts.Through tooth direction and tooth profile modification optimization of the drive axle gear,the maximum unit load on the tooth surface is reduced,and the stress distribution on the tooth surface is more uniform and reasonable,which improves the meshing performance of the gear.After optimization,the vibration harmonic amplitude of the drive axle decreases by about 26.17%,which weakens the vibration noise radiated outward in the gear drive process and achieves vibration damping and noise reduction of the electric drive axle.
